For example, there is a form of trading in which a retail electricity supplier purchases electricity whose price fluctuates according to time from the electricity market, etc., and sells the electricity based on a metered rate according to the amount of electricity used by the customer. Here, for example, if a retail electricity supplier sells electricity to consumers in a state where the metered rate is lower than the purchase price, the retail electricity supplier's profits will deteriorate. Therefore, it is conceivable to set a volume charge (selling price) that changes with time so as to correspond to the purchase price that changes with time.

However, calculating time-varying usage charges to correspond to time-varying purchase prices imposes a high computational load. Furthermore, in this case, when trying to identify the electricity rate of the consumer, the calculation process of multiplying the metered rate that fluctuates with time by the power consumption of the consumer at that time is performed for all consumers for all periods. Therefore, the load on the computer becomes extremely high.

Hereinafter, embodiments will be described in detail with reference to the accompanying drawings.
<System configuration>
FIG. 1 is a diagram showing the overall configuration of a control system for equipment to which this embodiment is applied. The control system of this embodiment includes a control device 100 and equipment 200 that is a controlled device. The control device 100 and the equipment 200 are connected via a network. This network may be a LAN (Local Area Network) using a dedicated line, a WAN (Wide Area Network), a VPN (Virtual Private Network) set on the Internet, or the like. The equipment 200 is equipment or equipment that operates using electric power. The control device 100 controls the operation of one or more pieces of equipment 200 . FIG. 1 shows a configuration example in which a control device 100 controls a plurality of equipment 200. As shown in FIG. The facility equipment 200 is of any type as long as it is equipment or equipment that operates using electric power and whose operation is controlled by the control device 100 . In the following description, as a specific example of the equipment 200, an example in which the control system of the present embodiment is applied to control air conditioning equipment may be described.

In addition, the facility equipment 200 has control means for controlling itself in accordance with the settings. The control device 100 generates control information for the equipment 200 to be controlled, and transmits the generated control information to each equipment 200 . Each facility device 200 acquires control information from the control device 100, configures its own device according to the acquired control information, and controls its operation by means of its own control means.

Also, the control device 100 is connected to a server 300 of a power retailer via a network. A retail electricity supplier is a business that purchases electricity in the electricity market and sells it to consumers. The server 300 provides the control device 100 with information on the purchase price of electricity (hereinafter referred to as “purchase price information”) and information on the selling price. For example, the Internet is used as a network that connects the control device 100 and the server 300 . Also, LAN or WAN may be used.

<Relationship between electricity rate and control of equipment 200>
Here, electricity charges will be explained. Electricity charges mainly consist of a basic charge and an electric energy charge, and are specified on a monthly basis. The basic charge is calculated based on the basic charge unit price and the contract power. The contracted power is the maximum value of the maximum demanded power within one year from the current month. The maximum power demand is the maximum value of the average power consumption for each time period (demand time period: 30 minutes) of the month. The average power consumption is the average value of power demand (power consumption) in each time period. Also, the power charge is calculated based on the power charge unit price and the monthly power consumption. In the following description, the electric energy charge is also referred to as the "quantity charge", and the electric energy charge unit price is also referred to as the "quantity charge unit price".

As described above, the contract power is the maximum value of the maximum power demand within the past year. Therefore, if the maximum demanded power in a certain month (in other words, the average power consumption for a certain time period in that month) becomes the contracted power, even if the maximum demanded power continues to be lower than the contracted power after that month, 1 A basic charge based on this contracted power will be charged throughout the year. In addition, if the average power consumption exceeds the contract power value up to that time in a certain time period and becomes the maximum power demand for the month that includes that time period, the average power consumption (maximum power demand) for this time period will be used as the new contract power. , to be used in the subsequent calculation of basic charges.

In addition, there are various modes of setting the power unit price, and the power unit price may be set to fluctuate based on a predetermined condition. For example, there are cases where the power unit price is set to fluctuate depending on the time of day, whether it is a weekday or a holiday, the season, and the like. In addition, electric power has come to be traded on the market, and a form has emerged in which retail electric power companies sell electric power purchased on the market to consumers. In such a form, there are cases where the power unit price is set to fluctuate by reflecting the transaction price of power in the market.

A retail electricity supplier purchases electricity on a time-limited basis in the electricity market and sells the purchased electricity to consumers. For this reason, the purchase price of electricity by a retail electricity supplier fluctuates for each time period. Here, in order for a retail electricity supplier to make a profit, it is necessary to sell electricity at a price higher than the purchase price. On the other hand, if the selling price becomes too high, consumers will lose the advantage of purchasing electricity from retail electricity suppliers. Therefore, the selling price of electricity is determined in consideration of the balance between the profit of the electricity retailer and the profit of the consumer. For example, it is conceivable to set a selling price (unit charge per unit price) that follows fluctuations in the purchase price for each period of time while maintaining a constant price difference with respect to the purchase price.

However, calculating the pay-as-you-go unit price that changes with each time period so as to follow the purchase price that changes with each time period imposes a heavy load on the computer. When such a metered charge unit price is set, the electricity bill for each consumer can be determined by multiplying the metered charge unit price, which fluctuates for each time period, by the power consumption of the consumer for that time period. It is necessary to perform the treatment for every customer for every period. Therefore, the load on the computer becomes extremely high.

As a means of avoiding this, it is conceivable to set a pay-as-you-go unit price that fluctuates at time intervals longer than the time limit unit while roughly following the purchase price. However, in this case, since the purchase price fluctuates irregularly on a time period basis, if the difference between the purchase price and the metered rate unit price is set to be small, the purchase price will exceed the metered rate unit price on the time period basis. , could result in losses for the retail electricity supplier. In this embodiment, in such a case, the control device 100 controls the operation of the equipment 200 for each predetermined unit time to individually reduce the power consumption, thereby minimizing the loss of the electricity retailer. Suppress the occurrence. With such control, the present embodiment roughly follows the purchase price instead of every time period, thereby suppressing an increase in the computer load for calculating the unit price per usage rate and the electricity rate for each consumer, and reducing the time period unit. , it is possible to suppress the occurrence of an event in which the purchase price exceeds the unit price of the metered charge. Below, the case where the control apparatus 100 controls the equipment 200 is demonstrated as an example using a time limit as a predetermined unit time.

Electricity charges are imposed on consumers who are contractors of power supply. A customer has one or more pieces of equipment 200 . The control device 100 controls one or a plurality of consumer equipment 200 . In addition, the control device 100 supplies the facility equipment 200 of each consumer with the average power consumption and power consumption per predetermined unit time according to the electricity charge (basic charge and power charge) set for each consumer. Perform control considering the charge unit price.

<Configuration of Server 300>
FIG. 2 is a diagram showing the configuration of the server 300. As shown in FIG. The server 300 is realized, for example, as a server built on a network cloud environment (so-called cloud server). Server 300 includes storage unit 310 and transmission unit 320 .

The storage unit 310 stores purchase price information and metered charge information of the sold electric power for each customer to whom the electricity retailer sold the electric power. The purchase price information is information on the purchase unit price of power purchased in the market by the retail electricity supplier on a time period basis. As the purchase price information, information correlated with the purchase price, such as a market price, may be used instead of the purchase price of electricity itself. The metered charge information is information related to the metered charge unit price of electricity sold by a retail electricity supplier in units of time limits. Although the details will be described later, the unit price for the usage rate is fixed for each time period for each day before the control of the equipment 200 for that day is started. Therefore, the metered charge information may be, for example, information representing the variation pattern of the metered charge for one day.

The transmission unit 320 transmits the purchase price information and the metered charge information stored in the storage unit 310 to the control device 100 that controls the facility equipment 200 of the consumer who has purchased power from the electricity retailer. The purchase price information and metered charge information to be transmitted are time limit information corresponding to power purchased by the consumer. Although details will be described later, the content of control for the facility equipment 200 is determined before the start of control on the day on which the control is performed. Therefore, the transmission unit 320 transmits the power purchase price information and metered charge information for each time period to the control device 100 before the control device 100 generates the control information specifying the control details for the day that includes the time period. Send.

<Configuration of control device 100>
FIG. 3 is a diagram showing the configuration of the control device 100. As shown in FIG. The control device 100 includes an information acquisition section 110 , a storage section 120 , a control information generation section 130 and an output section 140 .

The information acquisition unit 110 acquires various types of information used to generate control information for the equipment 200 . The information acquired by the information acquisition unit 110 includes purchase price information, metered charge information, information on power consumption for each consumer, and the like. The information acquisition unit 110 is an example of a purchase price information acquisition unit and an example of a metered charge information acquisition unit. Purchase price information and pay-as-you-go charge information are acquired from server 300 . As the information about the power consumption, for example, the contract power and the prediction information of the power consumption are acquired. The power usage forecast information is information about power usage in a future time period that is predicted based on past power usage records of consumers. Prediction of power usage may be performed by various existing prediction methods. For example, it is conceivable to accumulate the environmental information and operation information of the equipment 200 and the power usage record, and predict the power consumption from the environment and the operating state of the equipment 200 assumed in the future time limit.

Examples of environmental information include information on the environment in which the equipment 200 is installed, such as temperature and humidity. The operation information includes, for example, information representing operation states such as the operation rate and continuous operation time of the equipment 200 . In addition, various information that is considered to affect the operation of the equipment 200 can be used, such as the time zone in which it was operated, whether it is operated on weekdays or on holidays, and the like. The environmental information and the operating information are acquired from the installation location of the facility equipment 200, sensors provided inside the facility equipment 200, etc. according to the information to be acquired. Also, part of the operation information is acquired from the equipment 200 itself. The information on the time zone and operating days when the equipment 200 is operated may be input by the customer or the administrator of the equipment 200, or may be obtained from an external server or the like that provides date and time information. Depending on the type, scale, etc. of the facility equipment 200 to be controlled, different environmental information and operation information may be acquired as the information used to predict the power consumption. Various types of information are obtained via a network using, for example, a network interface (not shown).

The storage unit 120 stores various information acquired by the information acquisition unit 110 . The stored information is used when the control information generator 130 generates control information. The storage unit 120 also stores control information generated by the control information generation unit 130 .

The control information generation unit 130 generates control information for controlling the equipment 200 based on the information acquired by the information acquisition unit 110 . In the present embodiment, the control information generation unit 130 reduces the power consumption of the facility equipment 200 based on the relationship between the purchase price information and the metered charge unit price (power charge unit price), which is the selling price to the consumer. Generate control information for performing control oriented to The specific content of control specified by the control information varies depending on the type of equipment 200 . For example, when the facility equipment 200 is an air conditioner, resetting the set temperature of the cooling and heating for the time limit to be controlled so that the power consumption of the facility equipment 200 is reduced can be mentioned. Further, the control information generation unit 130 may generate control information based on other orientations in addition to the control information directed to lowering the power consumption. For example, control information oriented to the comfort of the user of the equipment 200 may be generated. The control information generated by the control information generation unit 130 is stored in the storage unit 120, and is generated at a predetermined time before the time limit for performing control based on the control information (in other words, the time limit for the control target based on the control information). , is sent to the equipment 200 to be controlled.

The output unit 140 reads the control information generated by the control information generation unit 130 from the storage unit 120 at a predetermined timing. Then, using a network interface (not shown), the read control information is output to the facility equipment 200, which is the object of control by each control information, via the network.

FIG. 4 is a diagram showing a hardware configuration example of the control device 100. As shown in FIG. The control device 100 is implemented by, for example, a computer. A computer that implements the control device 100 includes a CPU (Central Processing Unit) 101 as computing means, a RAM (Random Access Memory) 102, a ROM (Read Only Memory) 103, and a storage device 104 as storage means. A RAM 102 is a main storage device (main memory) and is used as a working memory when the CPU 101 performs arithmetic processing. The ROM 103 holds programs and data such as preset values, and the CPU 101 can directly read the programs and data from the ROM 103 to execute processing. The storage device 104 is means for storing programs and data. A program is stored in the storage device 104, and the CPU 101 loads the program stored in the storage device 104 into the main storage device and executes it. In addition, the result of processing by the CPU 101 is stored and saved in the storage device 104 . Further, the storage device 104 stores a learning model obtained by the above-described reinforcement learning, and is used for selecting the environment inside the refrigerator. As the storage device 104, for example, a magnetic disk device, an SSD (Solid State Drive), or the like is used.

It is realized by The storage unit 120 is realized by the RAM 102 and the storage device 104, for example. Note that the configuration example shown in FIG. 4 is merely an example of a case where the control device 100 is implemented by a computer.

<Configuration of equipment 200>
FIG. 5 is a diagram showing the configuration of the equipment 200. As shown in FIG. The equipment 200 includes a reception unit 210 , an operation control unit 220 and an output unit 230 . The equipment 200 has a mechanism or device that operates to realize the function of the equipment 200 according to its type. For example, when the equipment 200 is an air conditioner, the equipment 200 has an indoor unit, an outdoor unit, and the like. Moreover, when the equipment 200 is lighting equipment, the equipment 200 has a lighting fixture, a control switch, and the like. Since the types and modes of such mechanisms vary depending on the types of equipment 200, they are not illustrated here.

The reception unit 210 receives control information output from the control device 100 via a network using a network interface (not shown).

The operation control unit 220 controls operations of mechanisms and devices provided in the equipment 200 based on the control information received by the receiving unit 210 . Specifically, for example, when the facility equipment 200 is an air conditioner, the reception unit 210 receives information specifying the set temperature as the control information, and the operation control unit 220 controls the indoor unit and the air conditioner to achieve the received set temperature. Controls the operation of the outdoor unit. Although an example of control related to temperature setting is given here, the operation control unit 220 also controls various other types of control related to gases that can be controlled by air conditioning equipment (for example, control of humidity and gas components). Informed controls may be applied. Also, in various types of facility equipment 200 other than air conditioners, the operation control unit 220 executes control according to the type of facility equipment 200 according to control information received from the control device 100 .

The output unit 230 outputs information about the operating state of the equipment 200 to the control device 100 via a network using a network interface (not shown).

The receiving unit 210, the operation control unit 220, and the output unit 230 are realized by, for example, a computer. A computer that implements the operation control unit 220 may have the configuration described with reference to FIG. In this case, each function of the reception unit 210, the operation control unit 220, and the output unit 230 is realized by executing a program by the CPU 101 shown in FIG. 4, for example. Also, each function of the reception unit 210, the operation control unit 220, and the output unit 230 may be realized by dedicated hardware. For example, it is realized by ASIC (Application Specific Integrated Circuit), FPGA (Field-Programmable Gate Array), and other circuits. Furthermore, functions realized by CPU 101 executing a program (software) and functions realized by dedicated hardware may be combined to form reception unit 210, operation control unit 220, and output unit 230. FIG.

<Relationship between power market and control content of equipment 200>
In this embodiment, the facility equipment 200 is controlled to reduce the power consumption based on the purchase price information and metered charge information based on the power transaction by the electricity retailer. The electricity retailer purchases electricity in the market on a time-limited basis, identifies the metered rate unit price based on the purchased price, and stores it in the storage unit 310 of the server 300 . Therefore, the content of the control of the equipment 200 (the content of the control information generated by the control device 100) is specified according to the time when the electricity market opens.

FIG. 6 is a diagram showing the relationship between the power market and the determination timing of the control details of the equipment 200. As shown in FIG. The electricity market includes four types of markets, a forward market, a bulletin board market, a day-ahead market (spot market), and an hour-ahead market (intraday market), depending on the transaction time. Electricity used on a day (current day) including a time period to be controlled according to the present embodiment (target time period) is traded on these markets. The forward market and bulletin board market close a few days before the day, and the transaction price is fixed. The day-ahead market closes at 10:00 am on the day before the day to be controlled, and the trade price is fixed. The early market is traded up to one hour before the target time period of the current day. This early market is a market mainly used for power generation and demand adjustment on the day. Therefore, in the present embodiment, in principle, based on the trading results of the forward market, bulletin board market, and day-ahead market (spot market), before the start of control of the equipment 200 on the day, 200 is determined.

Here, the details of the control of the equipment 200 are determined based on the transaction price in the market other than the early market. On the other hand, if it is confirmed that power can be procured at a more favorable unit price in the early market after the details of the control are determined, the power is purchased in the early market, and the equipment 200 is controlled based on the transaction price. You can change the content.

<Method for Controlling Equipment 200>
Next, a method for controlling the equipment 200 will be described. As described above, the control system of the present embodiment performs control (hereinafter referred to as "suppression control") to reduce the power consumption of the equipment 200 based on the power purchase price and metered rate from the electricity retailer. conduct. Specifically, when the purchase unit price is higher than the metered charge unit price for a certain period of time, suppression control is performed (first control example). Further, when the purchase unit price is lower than the metered charge unit price and the difference is smaller than a predetermined threshold value, restraint control is performed (second control example). Each case will be described below with specific examples.

In addition, since the electricity charge is imposed on the consumer, if the consumer has a plurality of equipment 200, each equipment 200 may Control content is distributed by Therefore, for example, one facility device 200 owned by a consumer may be controlled, and another facility device 200 may not be controlled. However, in each example shown below, for the sake of simplicity, it is assumed that one customer has only one facility device 200 and the above suppression control is performed for each facility device 200 . Therefore, in each of the following examples, the control for reducing the power consumption of the consumer is suppression control for one piece of equipment 200 owned by the consumer.

(First control example) Control when the purchase unit price is higher than the metered charge unit price When the purchase price of electricity exceeds the metered charge, the electricity retailer suffers a loss from the sale of this electricity. In such a case, the control system of the present embodiment performs restraint control in the relevant time period in order to reduce loss.

FIG. 7 is a diagram showing the relationship between the pay-as-you-go unit price, purchase unit price, and suppression control in the first control example. In FIG. 7, for consecutive time periods 1 to 6, the values of the metered charge unit price and the purchase unit price, and information indicating whether or not they are subject to suppression control (denoted as "control target" in the figure) are described. The unit purchase price is the purchase price of power for each time period. In the example shown in FIG. 7, the set value of the metered charge unit price is 18 yen/kWh for time periods 1 to 3 and 20 yen/kWh for time periods 4 to 6. The purchase unit price is 10 yen/kWh for period 1, 14 yen/kWh for period 2, 25 yen/kWh for period 3, 13 yen/kWh for period 4, 15 yen/kWh for period 5, and 12 yen/kWh for period 6. kWh.

Comparing the unit price of the metered charge and the unit price of purchase for each time period, the unit price of the metered charge is higher than the unit price of purchase in periods 1, 2, and 4 to 6, but the unit price of purchase is higher than the unit price of the metered charge in period 3. there is Therefore, the control system makes time limit 3 the target of suppression control. In FIG. 7, information indicating that restraint control is to be performed (in the figure, a circle mark “◯”) is recorded in the control target item of time period 3 .

(Second control example) Control when the purchase unit price is lower than the metered charge unit price and the difference is smaller than a predetermined threshold Even if the purchase unit price is lower than the metered charge unit price, the purchase unit price and the unit price of the usage rate satisfies a predetermined condition, suppression control may be performed. For example, when the difference between the purchase unit price and the metered charge unit price is small, the profit that the retail electricity supplier obtains from the sale of electricity is also small. Therefore, it is conceivable to perform restraint control on the condition that the difference between the purchase unit price and the metered charge unit price is smaller than a predetermined threshold. In this case, not only suppression control but also adjustment control, which will be described later, is performed.

Inhibition control for reducing the power consumption of the equipment 200 is usually control for reducing the function of the equipment 200 . Such control reduces comfort and convenience for the user of the equipment 200 depending on the type of the equipment 200 . Therefore, if restraint control is performed in a certain time period, adjustment control may be performed in the next time period in order to restore the user's comfort and convenience. For example, when the facility equipment 200 is an air conditioner, after control to weaken the intensity of cooling and heating is performed as suppression control in a certain time period, in order to recover the comfort that has been lost due to the weakening of cooling and heating, cooling and heating is performed in the next time period. This is the case, for example, when control is performed to increase the strength of Since this adjustment control is a control for recovering the user's comfort and convenience that has been reduced by the suppression control for reducing the power usage of the facility equipment 200, the power usage of the facility equipment 200 is controlled in contrast to the suppression control. is controlled to increase There may be various aspects as to how much the power consumption is increased in the adjustment control, but here, the power consumption shall be increased by the same amount as the power consumption decreased by the restraint control.

It should be noted that the suppression control in this case aims at increasing profits, not suppressing losses at the retail electricity supplier. Therefore, if the difference between the purchase unit price and the metered charge unit price in the time limit for the suppression control is larger than the difference between the purchase unit price and the metered charge unit price in the time limit for the suppression control, even if the suppression control and the adjustment control are performed. good.

FIG. 8 is a diagram showing the relationship between the metered charge unit price, purchase unit price, power control amount, and power suppression control in the second control example. FIG. 8 shows, for continuous time periods 1 to 6, the values of the metered charge unit price and the purchase unit price, the control amount (adjustment value) of the power consumption by the suppression control and the adjustment control, and whether or not it is the target of the suppression control (control target). Information indicating whether A control amount is an amount by which power consumption is decreased or increased in suppression control and adjustment control. In the example shown in FIG. 8, the set value of the metered charge unit price is 18 yen/kWh for all of the time periods 1 to 6. In the example shown in FIG. The purchase unit price is 10 yen/kWh for period 1, 14 yen/kWh for period 2, 16 yen/kWh for period 3, 13 yen/kWh for period 4, 14 yen/kWh for period 5, and 12 yen/kWh for period 6. kWh. Also, the threshold for the difference between the purchase unit price and the metered charge unit price for determining whether or not to perform suppression control for a certain time period is assumed to be 4 yen/kWh (threshold).

Focusing on time limit 3, the purchase unit price is 16 yen/kWh and the metered charge unit price is 18 yen/kWh, so the difference is 2 yen/kWh, which is smaller than the threshold. Focusing on time period 4, which is the next time period after time period 3, the purchase unit price is 13 yen/kWh and the metered charge unit price is 18 yen/kWh, so the difference is 5 yen/kWh. Larger than the difference from the unit price. Therefore, by performing restraint control and adjustment control, the retail electricity supplier's profit increases more than when neither control is performed. In the illustrated example, the control amount (adjustment value) of the power consumption in the suppression control and adjustment control is 5 kW, the power consumption in time period 3 is decreased by 5 kW (-5 kW), and the power consumption in time period 4 is increased by 5 kW (+5 kW). I'm doing it. In addition, in FIG. 8 , information indicating that suppression control is to be performed (a circle mark “◯” in the figure) is recorded in the control target item of time limit 3 .

In the second control example described above, suppression control is performed on the condition that the difference between the purchase unit price and the metered charge unit price is smaller than a predetermined threshold. You may determine whether suppression control is performed based on the ratio between unit prices. As the ratio of the purchase unit price to the metered charge unit price approaches 1, the values of both unit prices become closer, so the profit that the retail electricity supplier obtains from the sale of electricity decreases. Therefore, suppression control may be performed on the condition that the ratio of the purchase unit price to the volume-based charge unit price is less than 1 and greater than a predetermined threshold. In this case as well, not only suppression control but also adjustment control is performed.
